----------------------------------

             Summary: Spark-sql do not support for column datatype of void in a HIVE view
                 Key: SPARK-20680
                 URL: https://issues.apache.org/jira/browse/SPARK-20680
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.1, 2.1.0
            Reporter: Lantao Jin


Create a HIVE view:
{quote}
hive> create table bad as select 1 x, null z from dual;
{quote}

Because there's no type, Hive gives it the VOID type:
{quote}
hive> describe bad;
OK
x	int	
z	void
{quote}

In Spark2.0.x, the behaviour to read this view is normal:
{quote}
spark-sql> describe bad;
x       int     NULL
z       void    NULL
Time taken: 4.431 seconds, Fetched 2 row(s)
{quote}

But in Spark2.1.x, it failed with SparkException: Cannot recognize hive type string: void
{quote}
spark-sql> describe bad;
